Please give me some advice if you have sent dry vegetables to the hotel.

Don't be too rigid in doing this. Treat the purchasing manager and the buyer as friends. Everything is easy to talk about. The most important thing is relationship! There is no fixed pattern!

Relationships, no matter what level, should be fully respected! If you respect them, everything will be easy.

There is no fixed standard for kickbacks, which is appropriate! You can grasp it if you have more contact!

Remember that "change makes sense".
